@LostVector Really appreciate your help. I tried those suggestions however I can't seem to get the RX480 and the 5k to work again like it was in 10.12.3. The terminal command was useful to know since I hadn't been doing that prior. I also made sure to enable dev-mode in my clover boot args which it wasn't. I eventually nuked all the board-ids from the config plist because after I couldn't get it working the first time (with only the relevant board-id removed) I kept switching around different Mac Definitions to test. (For Reference when it was working correctly on 10.12.3 I was using iMac17,1).

For now i'm using my nvidia 980ti because 5k is still working on that (back to having that cursed cursor glitch), just super frustrated I updated when everything was working so well :banghead:

I uploaded my Clover config plist, AGDP info plist, and a screenshot of the terminal command results if you have a chance to look at it or maybe could let me know if something looks incorrect to you. Anyway thanks again for all your help.
OK, I updated and lost 5K.

Turns out I may have missed something in my initial post. Make sure CFG_USE_AGDC is set to true in the plist for whatever accelerator.kext is used for your card. Probably in the default section, but if you are using a custom framebuffer then you might have to override it in the configuration section for that framebuffer. Still testing but that's when I got 5K back ...

aHa!!!! Totally working again! You were exactly right! That was the key to get it up and running again. And honestly I don't know how you figured that out because I would have never been able to find that out on my own in a million years. :clap::clap::clap:

Hello everybody.

I was wondering if there is any way to get R9 390X to work with dual displays in El Capitan without using iGPU as primary?
I already use a Sapphire Radeon HD 7790 Dual-X OC working with 2 displays one connected to HDMI port and the other is connected to DVI port and everything works just fine.

I've read somewhere in this forum using DisplayPort might work but since I don't have a HDMI to display port cable or any convertors at my disposal right now I thought someone might have a solution.

Thanks guys.

Hi Fl0r!an,

Thanks for the quick reply and your great topic.

When I boot with a single display attached everything works fine, but when I boot with second display connected both displays go dark.
When I boot with one display connected after OS is loaded then I attach the second display, both displays work fine.
I tried injecting ati=true and different farmebuffer settings it got worse.

@Fl0r!an
280X Saphire under El Capitan need IGPU enable like Sierra?
It's the only way I have to get desktop after black screen.

I checked and unchecked NO inject ati and any framebuffer or ID in config.sys

Anyone having color flashing issues with 10.12.4?
AMD Radeon HD6790 with modified Info.plist on AMDX3000 and AMD6000Controller, was working perfectly with 10.12.3.
@Ur-Quan said "setting RGBA8888 mode can solve this", worth a try!
